[V8] Un-explained cutting out

[W]

Have a '93 V8Q. Recently installed(myself) a new MAF sensor and had the A/C
charged at the service shop.  The car when cold will start and run, but
after a few blocks starts to stutter and then will cut off (dead). When it
first did this it started immediately and after it warmed, there appeared to
be no problem. The second time(yesterday) it cut off after a few blocks and
did not want to start initially but then it started. I had to race the
engine to keep it going.  It again died a couple of times. Finally got it
going and it seemed to stop the issue after it warmed up, but I took it home
as not be stuck out in the street. Could this be a problem with the ignition
reference sender or engine speed sender? I seem to remember if one them
malfunctions the car will not start or run. And these were both changed
about 5 years ago, even though I was not having a problem with them, it was
actually the fuel pump at that time. I only put about 3 to 4 thousand a year
on this car.  What could be the potential or most likely issues?
